Scat 5.7 Connecting Rods
 
What are the opinions of a Scat 5.7 Connecting Rod for a Super Stock application?
Thanks.

They may be fine, but I'd buy Manley's. Its a peace of mind thing.... spend it once, ya know. My original engine builder, convinced me, and I'm glad he did.

I better go find some wood to knock on , now that I said that......

You get what you pay for in most cases.
Any of them can fail. I pulled the eye out of a Manley connecting rod back in the 1990's. Manley did give me a new full set of rods but I still lost a block and a couple of pistons and cam in the deal.
My 2 Cents

yup...no matter what you buy, **** happens. I've seen them all fail...but if you check them when you get them completely/ big end / small end/ length/ Mag, you might ward off some problems...would'nt belive what I've seen in the past 35 years from all of them...

So true Bub...
Had a customer want to supply his own parts for a BB SS engine. He furnished all the parts. He did get a name rod, but they were out of parallel big end to little end about .006.
Try to explain that when checking the deck height. You have to check & recheck any brand.

Have a nice day

No Ed your not missing anything...properly prepared stock rod are just fine to a point. Piston weight and RPM will take a toll on any connecting rod...

All aftermarket rods are made in China. I believe Howards are the only ones left in USA. Ask Manley they will tell you the same.

I have used Scat rods in my bracket engine for years, and now my Super Stock engine. Never a problem. Wesley got them approved for me. I had to donate a sample rod. That is why Scat is listed. Wesley submitted it for me at the end of last summer.

I have had 2 460 ford motors ruined with eagle rods . they snapped in the middle of the rod.
I launched these motors at 1k rpm shifted at 5500 went thru traps at 6400.
both had less than 10 passes. I found out eagle is a chineese rod.. Same as scat
Never again!!!

They are both from China, but the Scat stuff is machined here. The engine builders I have talked to won't use Eagle. I know several that do use Scat. One uses them in all his circle track sbc engines and says he has never had a rod or crank failure. They get a lot of run time around 8000 RPM. I'm not easy on my stuff, and have no problems with the Scat rods.

Probably break one now that I've said that. <G>

I worked for SCAT as a buyer and bought the rods and various other components. SCAT owned the molds for the H-Beam rods and we were having them poured up in the valley. We never had any quality problems, core shift etc. All the machine work was done in house in Manhatten Beach CA. We did very little outsourcing (off shore) of components. All the cast cranks we machined were raw castings that did in fact come from abroad.

I used SCAT rods in my Super Stock 360 and never had any problem.

That makes me like them even better. Thanks.

I checked with my freinds at www.oliver-rods.com and they are 100 % MADE IN THE USA.

Has anyone used Crower rods? They cost several times what Scat does, but are NHRA listed for some apps where Scat isn't.

We have used them in some of the 400 sbc SS engines we have built.At the time they were the only ones who would build a custom length rod for you,and that is what a stock length 400 rod was considered at the time,custom.Now Manley has a pretty nice 400 rod also.

You can get Scat rods approved, but it will cost you one rod. Wesley did it for me, didn't take him long to get it done.

Re: Scat 5.7 Connecting Rods
 
Any of you guys ever use Ohio Crank stuff? I know that their cranks are forged over seas but machine at their facilities. I think they make their own rods. Got a 468 Pontiac stroker kit in my bracket car and a 489 BBC in my wifes car and they are still together. Good stuff.
